[0097]In the driving method of the flat panel display apparatus according to an embodiment of the invention, when at least the (1, N1)-th first wiring is selected and the signal voltage Vm(1, N1) is applied to each of the M second wirings, the predetermined voltage is applied to each of the M second wirings in the second second wiring group. That is, in the (1, N1)-th horizontal scanning period just before the signal voltage Vm(2, 1) is applied to each of the M second wirings, the signal voltage Vm(1, N1) has been applied to the first second wiring group and the predetermined voltage has also been applied to the second second wiring group. Therefore, in the (2, 1)-th horizontal scanning period, when the signal voltage Vm(2, 1) is applied to each of the M second wirings in the second second wiring group, since the second wirings have been in the pre-charged state, a dullness of the waveform of the signal voltage Vm(2, 1) which propagates in the second wirings (signal lines) is similar to a dullness of the waveform of the signal voltage Vm(1, N1). Thus, a difference is difficult to occur between the display state in the image display portion in the (1, N1)-th horizontal scanning period and the display state in th

Problems solved by technology

In the foregoing line-sequential driving system, the resolution of the flat panel display apparatus is rising more and more and problems, which will be described hereinbelow, occur due to a further increase in electrostatic capacitance in the second wiring and the realization of a further high frame rate.
Thus, a large difference occurs between the display state in the image display portion in the (1, N1)-th horizontal scanning period and the display state in the image display portion in the (2, 1)-th horizontal scanning period and a deterio

Embodiment 1

[0106]An embodiment 1 relates to a driving method of a flat panel display apparatus according to the first embodiment of the invention. As a flat panel display apparatus in the embodiment 1 or an embodiment 2, which will be described hereinafter, a flat panel display apparatus in which electron emitting devices have been assembled, specifically speaking, a cold cathode electric field electron emitting display apparatus (hereinbelow, abbreviated to a display apparatus) as a flat panel display apparatus in which cold cathode electric field electron emitting devices have been assembled is used.

[0107]As shown in a conceptual diagram in FIG. 1A, the display apparatus in the embodiment 1 or embodiment 2, which will be described hereinafter, has:

[0108](A) a first wiring group 113 (1131, 1132) constructed by N first wirings (specifically speaking, gate electrodes 13, which will be described hereinafter) extending in a first direction (specifically speaking, for example, horizontal

Example

Embodiment 2

[0125]An embodiment 2 relates to a driving method of a flat panel display apparatus according to the second embodiment of the invention. The flat panel display apparatus in the embodiment 2 has substantially the same construction and structure as those of the flat panel display apparatus in the embodiment 1.

[0126]In the embodiment 2, the first wirings are driven by the line-sequential driving system in which the first to Nth first wirings (gate electrodes 13) are sequentially selected. The Nth first wiring is selected and, subsequently, the first first wiring is selected. For a period of time until the first first wiring (gate electrode 13) is selected after Nth first wiring (gate electrode 13) was selected, the predetermined voltage is applied to each of the M second wirings (cathode electrodes 11). That is, after the (1, N1)-th horizontal scanning period in a certain frame was completed, before the first horizontal scanning period in the next certain frame is started, in

Abstract

A driving method of a flat panel display apparatus of a line-sequential driving system in which the display apparatus has N first wirings extending in a first direction, M second wirings extending in a second direction different from the first direction, and image display portions formed in overlapped regions of the first wirings and the second wirings, and the first to Nth first wirings are sequentially selected. A predetermined voltage is applied to each of the M second wirings for a period of time until the first first wiring is selected after the Nth first wiring was selected.
